Meet Our Trainers

MJ JOHNSTON

Hi! My name is MJ! I grew up in a small farming community in Missouri. I never felt like I fit in, and at an early age I realized I had dreams bigger than most of my peers. Once I finished high school, I originally went to school for fashion, but quickly realized this wasn’t the path for me. A spontaneous early-life crisis lead me to Boston, MA where I spent three years discovering who I was and what I wanted to do. During my first year here, I struggled with body image, confidence, and direction, which caused me to develop the female athlete triad. It took another full-year for me to recover, and find my love for health and fitness. Once I started toward my B.S in Sports Management through California University of Pennsylvania, I knew fitness/nutrition was the industry for me. I also discovered powerlifting during this time, and I will attribute my strength, both mental and physical, primarily to all my heavy lifting! By the time I graduated college, I made the move from Boston to Denver to open a gym exclusively for women and children.

It was a whirlwind when I moved to Denver; the dream I had of opening my own gym seemed so far away, but within two years of moving I made it happen. At this point, I have competed in five powerlifting meets, taking first place at all but one, and six bikini bodybuilding shows as a natural athlete. However, what I am the most proud of is my successful opened MJ Fit in the Denver Tech Center! Every day I go into the gym (even if it’s 5am), I am grateful for all the incredible women and kiddos who have trusted us with their health, and for my trainers who work tirelessly to provide the same level of service and dedication to their clients as I would. Oh, and I have two adorable pomsky puppies who pop in as “guest trainers” from time to time!

Why I’m a trainer: Once I found powerlifting, my entire life changed, and I made it my mission to help other women and children live healthier lives, allowing them to feel fulfilled too! At MJ Fit, our mission is “inspiring women and children to be strong,” and I love helping my clients find their “strong,” even when it is very different from my own. It is so rewarding to see a client reaching the goals we discussed months or years before in our consultation, and exciting to realize how team work is paying off!

Why I train myself: I have a background with personal insecurities leading to multiple eating disorders, the female athlete triad, osteopenia, and brittle broken bones. I finally decided this was not the life I wanted to lead. Once I discovered powerlifting, I fell in love and have now competed in several meets, taking home 1st place in all of them. I love seeing myself grow stronger, healthier, and more confident with each time I finish a workout.

Favorite Exercise: Squats! All of them, but mostly barbell back squats, because of how strong they make me feel. Plus, I can usually beat the boys! Click here to watch a video to learn how to do this badass exercise!

Fun Fact: I love to travel. I have ben to 10 countries so far, and am always planning my next adventure. If you need help with travel resources, I am your girl! Just make sure to bring me back a magnet!

DEB WITHINGTON

Hi I am Deb. I am originally from the East Coast but recently moved from St. Louis, MO. I credit my love for working out and my need to help others to a couple of pivotal moments in my life. The first pivotal moment was my early diagnosis with scoliosis as a toddler. As a toddler, I was not able to hold my head up straight. This led my parents to seek out leading specialists that believed in the power of exercise. Every night before going to bed, my mother would do exercises with me, and the great news is that it worked! I gained full mobility and strength avoiding the need for a back brace or surgery later in my childhood. From this experience, I learned the importance of early intervention and the power of exercise.

The second pivotal moment happened during my late teen years. I enrolled in the American Red Cross Water Safety Instruction program.  As part of this course, I was required to volunteer in the local community. I chose to volunteer at SLARC ( an organization that works with children with disabilities and their families). I loved being part of this organization so much that I took a part-time job there managing their free swim program.  During this time, I also began weight training and so my journey began to helping people become stronger, more independent and happier. This has been my lifelong passion. I am so excited that I can now do this as “my career” and I am excited about this new venture! Come join me on this ride!!!!

Why I’m a trainer: I became a personal trainer to give back to the community by helping people get stronger and feel better about themselves.

Why I train myself: Because it makes me feel good mentally and physically. My motto is “weights don’t disappoint.” They’re there to lift you up on a bad day and there to make a good day better.

Favorite Exercise: My favorite exercise is Bench Press! I love being able to max out my upper body strength because this strength is seen as a “men thing.” Click here to watch a video to learn how to do Bench Presses!

Fun Fact: I’ve been trained by the same person who trained Cory Everson, a famous bodybuilder from the 80s who won Ms. Olympia 6 times!

SHELBY NOLAN

Hi! I am Shelby. Although I’m a self-identified gym rat now, I did not start off athletic AT ALL! I struggled to feel confident with my figure and weight and was crushed by the misinformation I found in others and online. I had no evidence-backed guidelines to help me and didn’t know where or how to find them. I started doing Tough Mudders in 2013, and have, so far, done at least one a year since, but I still didn’t feel “fit”. In the fall of 2017 I finally decided, after failed attempts to work out at home or do yoga consistently, to start going to the gym and lift weights. This changed EVERYTHING! I went from being weak and “skinny” but with a higher body fat percentage to being able to deadlift more than my body weight in about a year! I was finally starting to LOVE my body and feel empowered! I also loved learning about health, strength, fitness, and nutrition, so I took courses and became a Certified Personal Trainer through NASM in January of 2019. What I would love to help others do, especially girls and young women, is become more confident in themselves through finding their strength and power in the gym so they can carry this self-assurance into other aspects of their lives. Confidence and mental health, especially in women and children, is the focus of my personal training (of myself and others). I also focus on building muscles (also called hypertrophy) to change the aesthetics of the body to fit the client’s desires. I have the most experience building the lower body, especially the glutes! If you’d like a perky, round booty, I have just the program for you! Together let’s get strong, get fit, and use this power in and out of the gym because “true strength comes from within” (that’s a reference for the fitness anime fans outs there)! Can’t wait to meet you!

Why I’m a trainer: I want to teach people that these “rules” of fitness are bogus. Fitness can be fun and fit into your lifestyle. It doesn’t have to be a painful struggle. My motto is “dedication without rigidity,” meaning you can be focused but not to the point that you have no more flexibility. Exercise can be such a benefit to mental health, but following bogus rules makes you feel trapped and like you’re failing. There is no fail/success dichotomy in fitness and exercise, and I want to share that.

Why I train myself: I train myself because I was always a passive person with no muscle mass. I did not think that “fit” was meant for me. I was a bookworm, a nerd, whatever. But once I picked up the weights, especially the barbell, I felt like such a strong, powerful person. And now I can’t stop learning about fitness and sharing with others when I can! We have so much more in us than we initially believe, but exercise can help show us our own inner strength.

Favorite Exercise: Hip Thrusts! They might look a little quirky, but they’re the best exercise to target just the booty.

Fun Fact: I’m in grad school for counseling, have two huskies, and LOVE anime!

TERRI ROSS

Hello! My name is Terri! I was born in Texas but raised in Denver, Colorado. I have been a cancer survivor since 2016, and through my journey toward recovery, I realized the power of exercise and self-care. Through all my treatments and appointments, I realized how much I missed feeling STRONG, so I made the commitment to myself to get all this back once I beat cancer. I started looking forward to empowering women to conquer the mind game of life through fitness. Now that I have gotten all the necessary certifications and training to be an MJ Fit personal trainer, I am eager to share my love of fitness and exercise with those around me. When I am not working or at the gym myself, I enjoy time hanging out with my Triathlon team, and family! I also enjoy physical challenges such as mud-runs, triathlon, and long bike rides. I live in Littleton with my husband and I have an 18 year old daughter who is attending CSU in Fort Collins!

Why I’m a trainer: I became a personal trainer because I noticed how quickly I could flip the script of a bad day by simply walking into the gym. I want to help women get confident in the gym so they can do the same.

Why I train myself: I train because it makes me feel confident. I love to make a goal and crush it. I also train because, when doing so, I am actively fighting cancer.

Favorite Exercise: If I can be outside I love to ride my bike. Otherwise, I like plyo drills such as box jumps and slam balls. Click here to watch a video to learn how to do box jumps!

Fun Fact: I’ve been skydiving but am afraid of bungee jumping.
